The bent rod 3, the limiting plate 6 and the locking switch 8 are made of high-strength insulating materials.
Working principle: when a plug is required to be inserted into a socket and locked: when the plug is not inserted into the socket yet, the sliding block 83 of the locking switch is ensured to be at the position of the second gear 82; the plug rod 91 is aligned to the jack 21 on the socket body 1 for insertion, and the curved rod 3 can be easily inserted because the top of the plug rod 91 is designed into an arc 912, and the curved rod 3 is clamped into the two grooves 911 on the plug rod 91 under the action of the tightening spring 5; when the sliding block 83 of the locking switch 8 is manually shifted to the position of the first gear 81, the sliding block 83 of the locking switch 8 pushes the limiting plate 6 to the curved rod 3, the triangular edge 61 of the limiting plate 6 firmly props against the curved rod 3 to fix the position of the curved rod 3, so that the curved rod 3 cannot rotate around the central shaft 4 any more, the two curved rods 3 are firmly clamped in the grooves 911 of the two plug rods 91, loose sliding and falling of the plug are further prevented, and the plug cannot be pulled out.
When the plug is required to be pulled out of the socket, the sliding block 83 in the locking switch 8 is only required to be manually pulled to the position of the second gear 82, the limiting plate 6 is pulled away from the bent rods 3 under the acting force of the limiting spring 7, and the two bent rods 3 can move again; at this time, the plug is pulled out to the outside, the two curved bars 3 can move along with the arc groove 911, the plug bar is released, the curved bars 3 are designed to be round, and the groove 911 is also semicircular, so that the plug is pulled out easily. When the plug is pulled out, the sliding block 83 of the locking switch 8 can be continuously moved to the position of the first gear 81, so that the bent rod 3 cannot be displaced. When it is necessary to insert the plug into the lock switch 8, the slider 83 of the lock switch 8 is moved to the position of the first gear 81. After resetting the crank 3, it is moved to the second gear 82 for subsequent operation.
